LOOSE-SHEET BINDER.

Application :filed January 10, 1921. Serial No. 436,140.

To all whom it may concer/n.'

Be it known that l, EDWARD J. SONNEN- nUno, a citizen 0f the United States, residing in Watts, in the county of Los Angeles and State of California, have invented a new and useful Loose-Sheet Binder, of which the following is a specification,

My invention relates to the art-of book binding, 'being more particularly a binder for holding loose folded sheets such as sheet music and the like.

. rThe principal objectA of my invention is toprovide a binder of the class described of simple form and construction in which sheets may be readily bound and easily removed.

@ther objects will appear from the following description and drawings.

Referring to the drawings which are for illustration purposes,

Fig. 1 is a face view of a binder embodying a form of my invention. showingV a folded sheet in place7 one leaf of the sheet being broken away,

Fig. 2 is a cross sectional view on a larger scale on line 2-2 Fig. 1.

Fig. 3 is an enlarged sectional view on line 3-3 Fig. 1.

Fig. 4 is a .fragmentary perspective view showing a portion of single sheet and binding rod.

Fig. 5 1s a cross sectional view of a portion of a binder showing a modified *formc of construction, and Fig. 6 is a similar view of a modified form of staple.

11 designates the back of the binder made of wood or other suitable stiff material covered with a flexible cove-ring material 12 to which is attached in the ordinary manner the front cover 13 and the back cover 14. Attached to the top and bottom of the back 11 in any suitable manner as by nails 15 are plates 16 forming retaining means for certain rods hereinafter referred to.

Secured to the back on the inside of the binder are twostaples 18, the points 19 of .the staples extending into the back 11 and the central vpart or 'bridge of the staples being spaced apart from the face of the back 11. 20,- 20 designate rods arranged to extend under. the staples 18 for the urpose of retaining the sheets designate at Secured to the inside of the back cover 14 is an envelope or container 22 for holding the rods 2() when not 1n use.

rllhe'binder is used in the"following manner; the folded sheet to be placed in the binder, in the form shown a music sheet is out out or notched at the folding line 23 as indicated at 24 such notches being spaced apart to correspond with the staples 18. rlhe folded portion of the sheet is then placed in the binder as shown in Fig, 1 the staples extending through the notches in the sheet. -When in this position a rod 20 is run under the staples along the folding line of the sheet thereby holding the sheet in place in the binder. rlfhe rod with the sheet thereon is slidable on the staples thereby permitting adjustment and the insertion and removal of additional sheets to and fro-m the binder. y

The retaining plates 16 preventdislodgment of the rods longitudinally but are not connected mechanically to the rods. A. sheet is removed from the binder by raising one end of therod holding the sheet above the plate 16 and withdrawing the rod from the staples/thereby freeing the sheet.

As shown in Fig. 2 the sheets in the binder lie flat being a particularly desir-able feature as the entire sheet is exposed except that portiondirectly under the rod 20.

ln Fig. 5 l have shown a modified form of staple indicated at 30, such staple forming substantially a half round, the back 31 having its inner faced. A v

ln Fig. 6 the sides of the back are provided With slots 35 into which the side men-1- bers 36 of the staple extend, the ends 37 of the staple extending from the sides into the back.

l claim as my invention:

1. A loose sheet binder comprising a back, a plurality of uniformly bent staples fixed at both ends to said `back having their central portion spaced apart from the back. arranged to extend through notches formed in the sheets, and a. loose rod consisting of a straight unbent wire for each sheet extending under the staples.

2. A loose sheet binder comprising a back. a plurality of staples fixed to said back arranged to extend through notches formed in the sheets, a loose rod extending under said staples engaging its associated sheetv along the folding line thereof, and means secured to the back of the binder beyond the ends of said rods for retaining said rods in said staples.l

face 32 correspondingly r28th day of December, 1920.

uniformly bent members fixed to said back at both ends arranged to extend throuvh notches formed in the folded edge of t e sheets, and a free rod consisting of a straight unbent Wire for each sheet extending under said members.

ln testimony whereof, I have hereunto set my hand at os Angeles, California, this EDWARD J. SONNENBURG.
